-------
|
||||
NOTE: This configuration compiles, but has not been fully tested
|
||||
on the hardware yet.
|
||||
|
||||
This configuration directory, performs a simple OS test using
|
||||
apps/examples/ostest with NuttX build as a kernel-mode monolithic
|
||||
module and the user applications are built separately. Is
|
||||
is recommened to use a special make command; not just 'make' but
|
||||
make with the following two arguments:
|
||||
|
||||
make pass1 pass2
|
||||
|
||||
In the normal case (just 'make'), make will attempt to build both user-
|
||||
and kernel-mode blobs more or less interleaved. This actual works!
|
||||
However, for me it is very confusing so I prefer the above make command:
|
||||
Make the user-space binaries first (pass1), then make the the kernel-space
|
||||
binaries (pass2)
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configuration using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
and misc/tools/
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. This is the default platform/toolchain in the configuration:
|
||||
|
||||
CONFIG_HOST_WINDOWS=y : Windows
|
||||
CONFIG_WINDOWS_CYGWIN=y : Cygwin environment on Windows
|
||||
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
||||
|
||||
This is easily changed by modifying the configuration.
|
||||
|
||||
3. At the end of the build, there will be several files in the top-level
|
||||
NuttX build directory:
|
||||
|
||||
PASS1:
|
||||
nuttx_user.elf - The pass1 user-space ELF file
|
||||
nuttx_user.hex - The pass1 Intel HEX format file (selected in defconfig)
|
||||
User.map - Symbols in the user-space ELF file
|
||||
|
||||
PASS2:
|
||||
nuttx - The pass2 kernel-space ELF file
|
||||
nuttx.hex - The pass2 Intel HEX file (selected in defconfig)
|
||||
System.map - Symbols in the kernel-space ELF file
|
||||
|
||||
4. Combining .hex files. If you plan to use the STM32 ST-Link Utility to
|
||||
load the .hex files into FLASH, then you need to combine the two hex
|
||||
files into a single .hex file. Here is how you can do that.
|
||||
|
||||
a. The 'tail' of the nuttx.hex file should look something like this
|
||||
(with my comments added):
|
||||
|
||||
$ tail nuttx.hex
|
||||
# 00, data records
|
||||
...
|
||||
:10 9DC0 00 01000000000800006400020100001F0004
|
||||
:10 9DD0 00 3B005A0078009700B500D400F300110151
|
||||
:08 9DE0 00 30014E016D0100008D
|
||||
# 05, Start Linear Address Record
|
||||
:04 0000 05 0800 0419 D2
|
||||
# 01, End Of File record
|
||||
:00 0000 01 FF
|
||||
|
||||
Use an editor such as vi to remove the 05 and 01 records.
|
||||
|
||||
b. The 'head' of the nuttx_user.hex file should look something like
|
||||
this (again with my comments added):
|
||||
|
||||
$ head nuttx_user.hex
|
||||
# 04, Extended Linear Address Record
|
||||
:02 0000 04 0801 F1
|
||||
# 00, data records
|
||||
:10 8000 00 BD89 01084C800108C8110208D01102087E
|
||||
:10 8010 00 0010 00201C1000201C1000203C16002026
|
||||
:10 8020 00 4D80 01085D80010869800108ED83010829
|
||||
...
|
||||
|
||||
Nothing needs to be done here. The nuttx_user.hex file should
|
||||
be fine.
|
||||
|
||||
c. Combine the edited nuttx.hex and un-edited nuttx_user.hex
|
||||
file to produce a single combined hex file:
|
||||
|
||||
$ cat nuttx.hex nuttx_user.hex >combined.hex
|
||||
|
||||
Then use the combined.hex file with the STM32 ST-Link tool. If
|
||||
you do this a lot, you will probably want to invest a little time
|
||||
to develop a tool to automate these steps.

/* The STM32F407VG has 1024Kb of FLASH beginning at address 0x0800:0000 and
|
||||
* 192Kb of SRAM. SRAM is split up into three blocks:
|
||||
*
|
||||
* 1) 112KB of SRAM beginning at address 0x2000:0000
|
||||
* 2) 16KB of SRAM beginning at address 0x2001:c000
|
||||
* 3) 64KB of CCM SRAM beginning at address 0x1000:0000
|
||||
*
|
||||
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
||||
* where the code expects to begin execution by jumping to the entry point in
|
||||
* the 0x0800:0000 address range.
|
||||
*
|
||||
* For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
|
||||
* FLASH and 4Kb of SRAM. That is an excessive amount for the kernel which
|
||||
* should fit into 64KB and, of course, can be optimized as needed (See
|
||||
* also configs/stm32f4discovery/scripts/kernel-space.ld). Allowing the
|
||||
* additional does permit addition debug instrumentation to be added to the
|
||||
* kernel space without overflowing the partition.
|
||||
*
|
||||
* Alignment of the user space FLASH partition is also a critical factor:
|
||||
* The user space FLASH partition will be spanned with a single region of
|
||||
* size 2**n bytes. The alignment of the user-space region must be the same.
|
||||
* As a consequence, as the user-space increases in size, the alignmment
|
||||
* requirement also increases.
|
||||
*
|
||||
* This alignment requirement means that the largest user space FLASH region
|
||||
* you can have will be 512KB at it would have to be positioned at
|
||||
* 0x08800000. If you change this address, don't forget to change the
|
||||
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
|
||||
* the check in kernel/userspace.c.
|
||||
*
|
||||
* For the same reasons, the maximum size of the SRAM mapping is limited to
|
||||
* 4KB. Both of these alignment limitations could be reduced by using
|
||||
* multiple regions to map the FLASH/SDRAM range or perhaps with some
|
||||
* clever use of subregions.
|
||||
*
|
||||
* A detailed memory map for the 112KB SRAM region is as follows:
|
||||
*
|
||||
* 0x20000 0000: Kernel .data region. Typical size: 0.1KB
|
||||
* ------- ---- Kernel .bss region. Typical size: 1.8KB
|
||||
* 0x20000 0800: Kernel IDLE thread stack (approximate). Size is
|
||||
* determined by CONFIG_IDLETHREAD_STACKSIZE and
|
||||
* adjustments for alignment. Typical is 1KB.
|
||||
* ------- ---- Padded to 4KB
|
||||
* 0x20000 1000: User .data region. Size is variable.
|
||||
* ------- ---- User .bss region Size is variable.
|
||||
* 0x20000 2000: Beginning of kernel heap. Size determined by
|
||||
* CONFIG_MM_KERNEL_HEAPSIZE.
|
||||
* ------- ---- Beginning of user heap. Can vary with other settings.
|
||||
* 0x20001 c000: End+1 of CPU RAM
